The change is due to our policy change on the 508 receivers. We have begun to charge the $6.00 monthly DVR fee for these receivers that we had been waiving up till 8-11. We have issued a credit equal to the amount of the change which will be on the account for the next 24 months which is in essence giving our customers 24 months notice that the account fee will be changing. I am not sure why you tax amount did not credit to your account and I will need to check you account and the state tax guidelines. If you would like my assistance on this, please feel free to PM me. Thank you!
